Feeds and Speeds Charts
Optimizing feed rates and speeds: 1. Start off using an RPM derived for the chip load for the material being cut (see charts). 2. Increase the cutting speed (feed rate) until the quality of the part's finish starts to decrease or the part is starting to move from hold downs. Then decrease speed by 10%. 3.

Preparing for hard metal milling
Tool selection, coolant strategy are critical for hard milling success. Unlike softer-state steels, milling hard materials favours toolpaths that have lighter depths of cuts, slower surface speeds, and decreased feed rates to combat the high cutting forces and large amount of heat produced.

How to Machine Acrylic: Get it Right the First Time!
You should also generally avoid tools with excessive radii (like round inserts) – this can cause rubbing if the feed is too low and then the surface finish will be cloudy. My go-to is a 0.060″ nose rad, since it's a nice balance between lighter cutting pressure and a good surface finish on turned diameters.

What is Cutting Speed,Feed,Depth Of Cut in Machine tools
The depth of cut is the distance that the tool bit moves into the work. usually measured in thouhs of an inch or millimeters. General machine practice is to use a depth of cut up to five times the rate of feed, such as rough cutting stainless steel using a feed of 0.020 inches per revolution and a depth of cut of 0.100 inch. which would reduce the diameter …
